hey guys... you guys are sooooo cool.... I was with a guy who fixes cameras but didn't know how to open this type of lens.... I've decided to send it to DAG....
thanks a lot for all the inputs.
Steve Grimes always said it was never a good sign
when you gave your Leica to a repairman who said,
"Oooh ! I've always wanted to work on one of THESE !"
good luck dx !
"One of the painful things about our time is that those who feel certainty are stupid,
and those with any imagination and understanding are filled with doubt and indecision"
I've disassembled a Type I Rigid Summicron, several collapsible Summicrons, Summitars, a Summar, and 9cm Elmars. I would vote to send a more modern lens to DAG, Essex, or Youxin Ye or other experienced person for cleaning.
I would not take apart the newer Leica lenses.
